CPT® Code 63275

The procedure described by CPT® Code 63275 involves a laminectomy performed specifically for the biopsy or excision of an intraspinal neoplasm located in the extradural space of the cervical region. An intraspinal neoplasm refers to a tumor that can be either benign, malignant, or of uncertain behavior, which means its potential for growth and spread is not clearly defined. In this surgical intervention, the neoplastic tumor is situated outside the dura mater, the protective membrane surrounding the spinal cord. The procedure begins with an incision made in the skin over the cervical area, where the tumor is identified. The surgical approach requires careful dissection to expose the lamina, which is the bony structure of the vertebrae, and the facet joint. A bone drill is utilized to remove part or all of the lamina, allowing access to the spinal cord and the tumor itself. Once the tumor is located, the surgeon assesses its extent to confirm that it is confined to the extradural tissue. A biopsy may be performed to obtain a tissue sample for pathological examination, which is crucial for determining the nature of the tumor. If the tumor is deemed excisable, the surgeon meticulously dissects it from the surrounding tissues, often using an operating microscope for precision. The procedure concludes with either the closure of the surgical site or the complete removal of the tumor, depending on the findings during the operation.
